Abstract

This document defines a PHB (Per-Hop Behavior) group called Latency
Loss Tradeoff (LLT). The LLT group is intended to provide delivery
of IP packets in two classes of services: a low-loss service (Lo
service) and a low-latency service (La service). The LLT group
enables an application to request treatment for either low-loss or
low-latency at a congested network link.
